Product Overview
The Platinum Cobalt Color 40 (HAZ 40) standard is a high-precision reference solution designed for accurate colorimetric measurements in laboratory settings. Formulated with platinum and cobalt salts, this standard adheres to the Pt-Co/Hazen color scale, ensuring consistent and reliable results for color intensity comparisons. The solution is calibrated to a 40 Hazen unit value, making it ideal for applications requiring precise color grading, such as water quality testing, chemical purity analysis, and industrial process control. Its stable composition minimizes degradation over time, providing long-term accuracy for repeated use. The analytical-grade purity ensures compatibility with spectrophotometric and visual comparison methods, while the 1000 ml pack size offers sufficient volume for frequent laboratory testing without frequent replenishment. This standard is particularly valuable in environments where color consistency is critical, such as pharmaceutical, environmental, and food testing laboratories.
FAQs
1. What is the shelf life of this platinum cobalt color standard?
When stored in a cool, dark place in its original sealed container, this standard typically maintains its accuracy for 24 months from the date of manufacture.
2. Can this solution be used for both visual and instrumental color measurements?
Yes, the HAZ 40 standard is suitable for both visual comparison using colorimetric tubes and instrumental analysis with spectrophotometers.
3. What materials are compatible with this color standard?
The solution is compatible with glass and most high-density polyethylene (HDPE) containers, but avoid prolonged contact with metals that may react with the platinum or cobalt components.
4. How should I handle spills of this color standard?
Absorb spills with inert materials like sand or vermiculite, then dispose of according to local chemical waste regulations, as the cobalt content requires proper handling.
5. Are there lower or higher concentration alternatives available in this series?
Yes, the platinum cobalt color standard series includes multiple concentrations (e.g., HAZ 5, HAZ 500) to cover a wide range of color intensity requirements.
